IMIROVEMENT IN MACHINE FOR LININ G PERCUSSION-CAPS.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, DERICK N. GOFI, of Wolcott-ville, in the county ofLitchfield, and State of Connecticut, have invented, made, and appliedto use, a certain new and useful improvement in Foil-Lining Percussion-Caps; and I do hereby declare the following to be a full, clear, andexact description of the said invention, reference bei'ng had to theannexed drawing, making part of this specification, wherein- Figure 1 isan elevation of my foil-lining machine, the bed, dies, and punches beingin section;' and Figure 2 is a sectional plan of the machine below theline mm.

Similar marks of reference denote the same parts,

Percussion-caps have heretofore been lined with foil by a punch that outout a disk of foil and pressed it down upon the fulminate in the cap.This rendered it necessary that the punch and the disk it cut out shouldbe smaller than the interior diameter of the cap, hence the edges of thefulminate were not always properly lined with the foil.

The nature of my said invention consists in a punch and die that out outa disk of foil rather larger than the interior of the cap, incombination with a punch that presses such disk to place in the cap, aspresented by a carrier-plate or slide. By this device the foil coversthe fulminatc in the most perfect manner, and extends to the interior ofthe cap, insuring a perfectly water-proof lining to the fulminate.

In the drawing (1 represents the bed of the machine, 6 a slide or platecontaining recesses or dies for the reception of the percussion-caps.This plate is moved progressively, 'so as to present the capssuccessively for the reception of the disk of foil, and thcn'to thepressing-punch, and for this movement any competent mechanism may beemployed. a is a head-block, in which the rods 01 slide vertically, asmoved by competent devices applied to the cross-bar e. f is a barbetween the rods d, carrying the punches g and h. The punch g acts tocut out a disk of foil from the strip 1' and force it through the die 0and deliver it within the percussion-cap beneath. The next movement ofthe plate 6 brings the cap to the punch It, to press said disk tightlydown upon the fulminate and properly line the cap, as aforesaid. Thestrip of foil 2' is supplied from a reel, is, or otherwise, and passesbelow the plate I that prevents the punch g lifting the same, and saidstrip is draivn along progressively by a pair of rollers, m, acted uponby a ratchet and pawl, n, moved by the rod 1). In order to prevent thedisk of foil adhering to the end of the punch g, I make use of pusher 1,that passes up through a hole in the punch g, and is of sufficientweight to deliver the disk into the cap after it is out out, but notheavy enough to injure the foil by resting upon the strip previous tothe disk being cut out.

What I claim, and desire to secure by Letters Patent, is-

The punch g, to cut out the disk of foil, in combination with thepressing-punch h, and mechanism for prosenting the percussion-cupssuccessively, substantially as ,set forth.

In witness whereof I have hereunto set my signature this fourteenth dayof March, 1867.
